Sugihara Hirohiro (Dowada Hideki) is a hearing impaired patient. Because of his weak hearing, Hangping often makes suspicious actions and is treated differently by others. Over time, Hangping learns to hide his thoughts, stay away from the crowd and right and wrong, and live in a world of his own. One day, a man named Sagawa Taiichi (Ono Temple Kuo Liang) broke into the closed world of Hangping. Taiyi did not deliberately avoid the problem of hearing loss in Hangping, as if it were a normal thing. Taiyi's frankness slowly infected Hangping, at the same time, Hangping's inner feelings for Taiyi were also awakened. Hangping's hearing is inevitably getting worse every day. Can he communicate with Tai Yi before he completely loses his hearing?
